详细信息:ApopNexin Annexin V FITC Apoptosis Kit.The ApopNexin™ FITC Apoptosis Detection Kit is designed to detect a specific biochemical change in the cell surface membrane that is considered to be a signature event of early apoptosis. These kits contain Annexin V conjugated with FITC, allowing for convenient quantitative assays. The counterstain, propidium iodide (PI), can be used to distinguish apoptotic cells with intact membranes from lysed, necrotic cells. These reagents must be used on live cells and are not applicable to previously sectioned, scraped, fixed or permeabilized cell samples. However, treatments that impact the cell membrane can be performed after the ApopNexin™ protocol.
